Whirlpool Dishwasher Clean Light Blinking: 10-1... | appliancefaults.com

Technical Background:

The dishwasher's Main Control Unit (MCU) monitors the turbidity sensor signal to determine water cleanliness. The sensor sends a voltage signal back to the MCU, and the MCU interprets this signal to adjust the wash cycle. A 10-1 error code indicates that the MCU has detected an out-of-range signal from the turbidity sensor, suggesting the water is not clean enough, or the sensor is malfunctioning. Voltage typically is 5V DC to the sensor, with a return signal between 0.5V and 4.5V depending on water clarity.

Symptoms:

The homeowner reports that the “clean” light on their Whirlpool dishwasher is blinking and the dishwasher isn't completing its cycle. They may also observe the dishwasher stopping mid-cycle.

Possible Causes:

Faulty turbidity sensor.
Wiring harness issue to the turbidity sensor.
Issue with the main control board.
Debris buildup affecting sensor readings.
Low water pressure during the cleaning cycle.

Solution:

1

Disconnect power to the dishwasher at the breaker panel.
2

Locate the turbidity sensor in the sump area; it's usually a small, cylindrical component.
3

Inspect the wiring harness connected to the turbidity sensor for any damage or loose connections.
4

Using a multimeter, check the sensor's resistance. A typical value is between 1000-3000 ohms (refer to the service manual for exact specifications).
5

Clean the turbidity sensor with a soft brush and mild detergent to remove any debris.
6

Reconnect the power and run a test cycle. Observe if the error code reappears.
7

If the error persists, replace the turbidity sensor or the main control board. Use a 1/4-inch nut driver to remove the sensor.

Safety Warning:

Always disconnect power to the appliance at the breaker panel before performing any repairs. Lock Out/Tag Out (LOTO) procedures should be followed to prevent accidental re-energizing of the circuit. Some components may retain a charge even after disconnection.

Prevention:

Regularly clean the dishwasher filter and ensure adequate water pressure to prevent debris buildup and maintain proper sensor function. Run a dishwasher cleaner cycle monthly.

Expert Tip:

Many Whirlpool dishwashers have a diagnostic mode. Press the following buttons in quick succession: High Temp Wash, Heated Dry, High Temp Wash, Heated Dry. This will enter the diagnostic mode, which may provide more specific error information. The diagnostic codes can then be looked up using the tech sheet in the kick panel.

Frequently Asked Questions

•What is the typical lifespan of a turbidity sensor in a Whirlpool dishwasher?

The typical lifespan of a turbidity sensor is around 5-7 years, depending on water quality and usage frequency.

•How do I access the diagnostic mode on my specific Whirlpool dishwasher model?

The diagnostic mode entry sequence varies between models. Refer to the service manual for the correct sequence for your specific model. It's often found inside the dishwasher's kick panel.

•What is the resistance value range for a properly functioning turbidity sensor on my Whirlpool dishwasher?

The resistance value varies by model. Consult the service manual or technical specifications for your specific Whirlpool dishwasher to determine the correct resistance range. It's typically between 1000 and 3000 ohms.
